Alas my game PC is going to stick with Windows due to bad state of VR in Linux :/. And therefore one day it might need to update to Windows 11.
In particular if you have a headset that is not Valve Index, though apparently with Meta Quest one can use ALVR, as long as you get the actual games running.
So the trick is to use the
#fragment
part of the URL, that is not sent to the server.Of course the JS one downloads from the server could easily upload it to it, so you still need to trust the JS.
